Harvard Business School professor Francesca Gino is accused of fraud. Here's how it happened

Francesca Gino is accused of falsifying data in four of her published papers.

The Harvard Business School professor is on "administrative leave" from his job as an office assistant.

The first time I was on the periphery of a large-scale fraud was when I was a teenager in the 2000s .

Paul Graham : When I was a teenager, I thought I was looking at the clean files of an honest and hugely successful investor, then looking out the window at the followers of inspirational sports hero Lance Armstrong .

Graham : The common thread that unites all of these frauds is ambition.

Ambition has always been part of our human nature, but it has not always possessed the strongly positive connotation it enjoys today , he says.

Frida Ghitis: Ambition is part of the air we breathe in the middle and upper classes of America today .

She says it's possible for a normal person to get caught up in the ways of ambition.

Ghitis writes that even after achieving great glory, she was unable to fix the limits of her CV.
